YES

Seriously if this was our main method for roof cleaning I would be bankrupt, forget a harness I would want a straight jacket 

The job has taken 2 days, if it was washable, we would of completed it in a day.

No I didn't use algo clear

Chris, when you carry out a 'soft' wash when the tiles are damp / wet, do you use a pressure wash to rinse down ?

[chris scott]

Mike...Don't really understand the question.This is what we do.
When soft washing I keep everything as dry as possible and use back pack blowers to "tidy" up .The moss is relatively easy to deal with wile dry and the clean up is quick. Roof and gutters can be blown onto the floor and bagged. Downspouts are also blown out with the backpack. 
We carry out the chemical application last ...after everything  is tided up
We mix the Algoclear with water  on site and then apply. A damp surface is actually better as the chemical is more readily absorbed than if the surface was dry. Much like the difference between a dry sponge and a damp one.A dry one (sponge) will repel water a damp sponge will absorb water quickly till the point of saturation.Similar with moss and algae
We then wash the fascias, soffits ,gutters down with the soft wash machine as we clean it out...Algoclear is actually a very strong surfactant so the plastics gleam!
The product we use is called Algoclear

What tools have you found work best for mos scraping? Just a stiff brush and a plastic scraper?

[chris scott]

Yep things like that ..we use paint scrapers for the tile overlap gap.

Sorry, have you turned into Kevin  

The roof which started this topic was due to be pressure washed, however once I got onto the roof it became apparent the tiles were far to soft and thin for washing  (std concretes house was built in the 40's) . I recommended to the customer to replace the roof, forget the clean, however as this job had been booked for over 4 wks I felt obliged to help them out, as they want to place the property up for sale hence the clean.

I gave them the option of the so called soft wash, weather was crap combination of light rain and fog, hence tiles were soaked. Initially tried hard brush - would not touch the moss so we had to use wire brushes. Impossible to brush all of the moss off as it was soaking wet so once the main lumps were removed we had to rinse the roof down using pressure washer to remove the remaining loose moss. As the guttering was already full of water due to the rain and we had blocked the down pipes, the clean up was very similar to when we wash via pressure washing. Conservatory had to be cleaned blah blah.

I can see how its possible to clean the way you advise on a dry summers day but in rain or winter its nonsense

[chris scott]

I would not clean a roof if it is Knackered ...I would then be to blame for any subsequent problems.
I tend not to clean roofs in the rain ..due to it washing off the Algoclear  .
I  have a Mosmatic  I use when "pressure washing" roofs

Why have I turned into Kevin? You asked a question (which I did not really understand) and answered it as I saw fit. Giving you an insight in to how we go about it and the reasons behind it. I thought my answer was pretty comprehensive.

Your nothing like me!!!  I understand everything and I am good looking as well

We're not in the US guys where soft washing shingle roofs is the norm.

If you're scared of getting up there and washing them properly, you think you're gonna do a proper job scraping it? If you gained the experience washing roofs you'd understand how difficult even that method can be let alone scraping and expecting some bullshiit branded algaecide lighten it for you.
Either learn to do them properly and repair, re-bed and repoint and/or additional seal/coating or leave it to those experienced, otherwise deal with the hassle of an insurance claim when you fall through the roof. Most of you don't even know how to walk on a roof. So learn to walk before you run.

That may or may not be true regarding Mr Scott but not true in my case!  Considering my Dad had a Roofing Business all his life!  I think being sent up my first roof at the age of 13 (45 Years ago) and carrying full packs of slates up within 6 months with no scaffold (In those days).  I certainly have a lot of experience walking on roofs.  As to roofs themselves I can strip, felt, rebatten and retile as well as rebed, repair, flash and repoint with tiles or slate.  (I may have to borrow a younger set of knees though because mine are knackered from laying tiles and natural stone on floors)   Which is why I got into Restoration
